Yuav Ua Li Cas Dissolve HPMC kom raug?

Kev ua kom raug Hydroxypropyl Methylcellulose (HPMC) yog qhov tseem ceeb los xyuas kom meej tias nws muaj txiaj ntsig zoo rau hauv cov qauv.Nov yog cov lus qhia dav dav rau kev rhuav tshem HPMC:

1. Siv dej huv:

Pib nrog dej huv, chav tsev kub kom yaj HPMC.Tsis txhob siv dej kub thawj zaug, vim nws yuav ua rau clumping lossis gelation ntawm cov polymer.

2. Ntxiv HPMC Maj mam:

Maj mam sprinkle los yog sift lub HPMC hmoov rau hauv dej thaum stirring tas li.Tsis txhob muab tag nrho cov nyiaj HPMC tso rau hauv dej ib zaug, vim tias nws tuaj yeem ua rau clumping thiab tsis sib xws.

3. Sib Nqus Zog:

Siv lub tshuab ua kom siab ceev, immersion blender, lossis mechanical stirrer los sib tov HPMC-dej sib tov kom huv si.Xyuas kom meej tias HPMC cov khoom tau tawg tag nrho thiab ntub dej los ntawm dej kom yooj yim hydration thiab dissolution.

4. Cia sij hawm txaus rau dej:

Tom qab sib tov, cia lub HPMC hydrate thiab o nyob rau hauv dej rau lub sij hawm txaus.Cov txheej txheem hydration yuav siv sij hawm nyob qhov twg los ntawm ob peb feeb mus rau ob peb teev, nyob ntawm qib thiab particle loj ntawm HPMC, nrog rau cov concentration ntawm cov tshuaj.

5. Kub yog tias tsim nyog:

Yog tias tsis ua tiav kev ua tiav nrog cov dej kub hauv chav tsev, cov cua sov maj mam tuaj yeem siv los ua kom yooj yim rau cov txheej txheem so.Tshav kub HPMC-dej sib tov maj mam thaum nplawm tas li, tab sis tsis txhob npau taws lossis kub dhau, vim tias lawv yuav degrade cov polymer.

6. Txuas ntxiv mus txog qhov tseeb daws:

Txuas ntxiv sib xyaw HPMC-dej sib tov kom txog thaum tau txais cov tshuaj ntshiab, homogeneous.Tshawb xyuas cov kev daws teeb meem rau ib qho lumps, clumps, lossis undissolved particles ntawm HPMC.Yog tias tsim nyog, kho qhov sib tov nrawm, lub sijhawm, lossis qhov kub thiab txias kom ua tiav kev sib cais.

7. Lim yog xav tau:

Yog hais tias cov tshuaj muaj tej yam undissolved hais los yog impurities, nws muaj peev xwm lim los ntawm ib tug nplua mesh sieve los yog lim ntawv kom tshem tawm lawv.Qhov no yuav xyuas kom meej tias qhov kev daws teeb meem kawg yog dawb los ntawm ib qho teeb meem me me thiab tsim nyog rau kev siv hauv formulations.

8. Tso cai rau kev daws kom txias:

Thaum HPMC tau yaj tag, cia cov tshuaj kom txias rau chav sov ua ntej siv nws hauv cov qauv.Qhov no yuav xyuas kom meej tias cov kev daws teeb meem nyob ruaj khov thiab tsis dhau ib theem kev sib cais lossis gelation thaum khaws cia lossis ua haujlwm.

Los ntawm kev ua raws li cov lus qhia no, koj tuaj yeem yaj HPMC kom ua tiav cov kev daws teeb meem zoo ib yam tsim nyog rau kev siv ntau yam, xws li tshuaj, khoom siv, khoom siv tu tus kheej, thiab daim ntawv thov zaub mov.Kev hloov kho rau cov txheej txheem sib tov yuav tsim nyog raws li cov kev cai tshwj xeeb ntawm koj cov qauv tsim thiab cov khoom ntawm qib HPMC siv.
